估计论坛里没几个人知道zigzag指标里这个问题的答案 新评论 zbj 2012.05.16 03:17 在zigzag指标代码中，有这样一段代码，请问，为什么要判断二次 counted_bars==0 ？第一次counted_bars==0 && downloadhistory和第二次counted_bars==0的作用是什么？ if (counted_bars==0 && downloadhistory) // history was downloaded { ArrayInitialize(ZigzagBuffer,0.0); ArrayInitialize(HighMapBuffer,0.0); ArrayInitialize(LowMapBuffer,0.0); Print(counted_bars); } if (counted_bars==0) { limit=Bars-ExtDepth; downloadhistory=true; Print(counted_bars); } MT4 IndicatorCounted() 函数和官网ZIGZAG指标 自己写的代码~运行不了，求高手帮忙检查一下bug在哪里~ Array out of range exception when debugging 新评论
在zigzag指标代码中，有这样一段代码，请问，为什么要判断二次 counted_bars==0 ？第一次counted_bars==0 && downloadhistory和第二次counted_bars==0的作用是什么？
if (counted_bars==0 && downloadhistory) // history was downloaded
{
ArrayInitialize(ZigzagBuffer,0.0);
ArrayInitialize(HighMapBuffer,0.0);
ArrayInitialize(LowMapBuffer,0.0);
Print(counted_bars);
}
if (counted_bars==0)
{
limit=Bars-ExtDepth;
downloadhistory=true;
Print(counted_bars);
}
